Welcome to Federal Signal Headquarters 

Rip.

They weren’t replaced, they still exist as in FS still makes them

sirenfan97 they actually did as on the pull there the modulator is there is a DSA

Weird these Sirens are jacked up the ones that I normally see

Modulator siren is cool, but looks like white hockey pops siren.

Hey stop it

shodowhater Really?

YEE.

yee

no, the modulator replaced it. For something as prestigious as the Thunderbolt, you would think FS would put that front and center as the first demo siren you see when you enter the complex.

shodowhater h

0:19 Hey, look! A Modulator! Let's see it!

ChicagoSirens i hope so

They go off for different reasons so no.

Yes. They working good and sound all of them.

no the others are used for demo purposes the 2001 does though

P-50 dude I don't know. Sorry! :(

Shut up giant barf bucket

P-50 dude University Park Illinois

There

TommyBNSF can you record all of these sirens activated?

No. It looks like white hockey pops siren.

They're tested every month for the Illinois Statewide Monthly Tornado Drill.

***** But then why the hell are they so close together then??? They MUST be used for demo use as well to right for potential buyers who want to see the different models that Federal has to offer.

Um no actually they are really used and hocked up to a siren system they don't need customers coming to the plant to hear them because they already have recording demos of each of their sirens on every sirens product info page the recordings are of all tones that that siren produces.

SixR Um no. A siren system does not have a siren and then another siren 50 feet away like this. An actual system has the sirens spaced out very far apart from each other because sirens can be heard from a great distance away. Why the hell would you have a system were the sirens are 50 feet away from each other??

Um yes they can and be really hooked up to a system and be within 50 feet apart from each other there's this one town that has a Whelen wps 2809 and a Whelen 4004 within a 50 foot radius of each other and they are both connected to the same system they did that so they can increase the decibel levels and increase the distance they cover so don't tell me other wise also it's not against regulations for a town to do this this video proves that it's not against regulations to do so federal most likely has these sirens within a 50 foot radius so they can be used to warn the workers that work inside the factory while using all of these at the same time.

My thoughts exactly lol

Chris Graddy yes they do all of them together I'm not sure when though

They test them once in a while. Maybe once a year or twice a year

No because there just has a walkthrough

Even WHYS THERES A WHELEN

Matthew Ly there is a video of these things going off at once.
